Description

Technical Field

[0001] The utility model relates to the technical field of graphitization furnaces, in particular to a power transmission vehicle with strong versatility. Background Art

[0002] With the development of the economy and the continuous changes in energy structure, AC graphitization furnaces are used more and more in industrial production. The power transmission car is one of the important equipment necessary in its production process. The convenience and reliability of the power transmission car is particularly important in production.

[0003] AC graphitization furnaces operate intermittently. A single production cycle involves loading, powering on, cooling, unloading, and overhauling, taking a total of 12 to 15 days, with powering on for only 3 to 5 days. Generally, one transformer can be used to power 5 to 7 furnaces of the same specifications, forming a furnace group, which is a production unit. During production, the transformer operates continuously, and the furnaces operate in turns. Typically, one furnace in a furnace group is powered on, while the others are being loaded, cooled, loaded, unloaded, or overhauled. After one furnace is finished operating, power is supplied to the next. A track is typically laid in front of each furnace group, and a power supply car travels on the track, connecting the furnace head electrode to the busbar of the furnace to be put into operation as needed. After the power supply and heating are completed, the power supply car disconnects the furnace head electrode from the busbar and moves to the next furnace to be operated to connect the furnace head electrode to the busbar.

[0004] Existing conductive devices typically use fixed power connections, such as clamping connections. While reliable, these connections have limitations in practice. In high-temperature or high-vibration environments, clamping connections can lead to unstable power transmission due to poor contact. They also struggle to adapt to changing environmental conditions, such as high temperatures and vibration, limiting their application. Furthermore, clamping connections are complex to maintain, requiring regular inspection and replacement of worn parts, increasing maintenance costs.

[0005] Most power transmission vehicles currently on the market use traditional chain or gear drives to transmit power. However, these traditional designs have several limitations: Chain or gear drive systems contain numerous mechanical components, which are susceptible to wear and tear after long-term use, requiring regular maintenance and replacement, increasing maintenance costs. Chain and gear drive systems also experience energy losses during the energy conversion process, reducing the overall efficiency of the power transmission vehicle. Furthermore, these systems generate significant noise during operation, impacting the comfort of the working environment.

[0006] In order to solve the above technical problems, the present utility model designs a power transmission vehicle with strong versatility. Utility Model Content

[0029] As Figure 1 and Figure 2 shown, a trolley with strong versatility is characterized in that it includes a vehicle body 1, a lower support body 2, a support vehicle body 3, an upper support body 6, and a push-pull type power connection mechanism that is mirror-symmetrical, and the push-pull type power connection mechanism makes two power connection plates respectively fit with the furnace head electrode and the busbar; a driving mechanism for moving the two power connection plates in the push-pull type power connection mechanism is arranged on the lower support body 2;

[0030] The lower support body 2 is slidably connected to the vehicle body 1, the push-pull type power connection mechanism is installed on the lower support body 2, the upper support body 6 is installed on the top of the lower support body 2, the support vehicle body 3 is installed on the vehicle body 1 and is slidably connected to the vehicle body 1, the push-pull type power connection mechanism is installed on the support vehicle body 3, the vehicle body 1 includes a vehicle frame, a battery pack, and wheels, a motor is fixedly connected to the vehicle frame, and the wheels are installed at the bottom of the vehicle frame. The direct drive method reduces the loss during the energy conversion process, is more efficient than chain drive, has lower noise, and higher reliability.

[0031] As Figure 3As shown, the push-pull power connection mechanism includes a first power connection module 4 and a second power connection module 5 arranged vertically. The first power connection module 4 includes a first power connection plate 41, a connecting member 43, and a second power connection plate 44. Both ends of the connecting member 43 are respectively connected to the first power connection plate 41 and the second power connection plate 44 through a connecting plate 42. The connecting member 43 is made of a flexible material. The second power connection module 5 has the same structure as the first power connection module 4. The connecting member 43 is made of a copper flexible strip. The connecting member 43 being a flexible material is mainly used to adjust the power connection distance to ensure good electrical connection under various working conditions. The connecting member 43 can be stretched or tightened according to actual needs to adapt to the power connection requirements at different positions, ensuring the free movement of the power connection trolley on the track. By allowing a certain degree of displacement, the flexible connecting member 43 can ensure stable electrical connection even when there are minor changes in the furnace structure.

[0032] The driving mechanism is an opposed double-piston oil cylinder 45. The cylinder body of the opposed double-piston oil cylinder 45 is connected to the lower support body 2, and its two piston rod output ends are respectively connected to the first power connection plate 41 and the second power connection plate 44. The internal structural feature of the opposed double-piston oil cylinder 45 is that it has two pistons arranged face to face, and these two pistons share a hollow oil cylinder barrel. When hydraulic oil is input to one end of the oil cylinder, the corresponding piston will be pushed forward, while the piston at the other end will move in the opposite direction under the action of spring force or other reaction forces. This design enables the opposed double-piston oil cylinder to achieve two-way synchronous movement, that is, the two pistons can simultaneously and relatively extend and retract. Placing the two pistons in the same oil cylinder in the opposed double-piston oil cylinder 45 can significantly reduce the required installation space. The opposed double-piston oil cylinder 45 is installed on the cross beam in the middle of the lower support body, and the free ends of the two piston rods drive the support plate 21, the first power connection plate 41, and the second power connection plate 44 to move and press against the busbar and the electrode.

[0033] Alternatively, the driving device can be two single-piston oil cylinders with opposite directions.

[0034] As Figure 4 As shown, the support vehicle body 3 includes a vehicle body plate 31 and support wheels 32. The support wheels 32 are fixedly connected to the bottom of the vehicle body plate 31. A first support column 33 and a second support column 34 are fixedly connected to the vehicle body plate 31. The support wheels 32 are universal wheels. The first support column 33 and the second support column 34 are used to provide stability and support for the push-pull power connection mechanism. The support columns can ensure that the flexible part is in the correct position, avoiding deviation or swing caused by external factors such as vibration or wind force, and helping to reduce the vibration of the flexible part, thereby reducing electrical connection problems caused by vibration, such as poor contact or disconnection.

[0035] The lower support body 2 includes a support plate 21 and lower support wheels 22. The lower support wheels 22 are connected to the bottom of the support plate 21. The lower support wheels 22 are directional wheels, also known as guide wheels, which are mainly responsible for guiding the push-pull power connection mechanism along a specific direction. The lower support wheels 32 are universal wheels, which provide omnidirectional movement capabilities. When both the support wheels 32 and the lower support wheels 22 are set as directional wheels, when there is a deviation in the directions of the two directional wheels, it will cause the push-pull power connection mechanism to jam, that is, the push-pull power connection mechanism cannot move. Therefore, the design of universal wheels plus directional wheels can reduce problems caused by improper steering or inaccurate positioning. This design can reduce the maintenance frequency and cost.

[0036] A partition column 35 is arranged between the first support column 33 and the second support column 34. The partition column 35 separates multiple connecting pieces 43, enabling the connecting pieces 43 to move stably between the first support column 33 and the second support column 34.

[0037] As Figure 5 shown, the upper support body 6 includes an upper support beam 61, a sliding mounting seat 62, and a pulley 63. The sliding mounting seat 62 is detachably connected to the lower support body 2. The pulley 63 is in rolling connection with the sliding mounting seat 62, and the pulley 63 is in sliding connection with the support beam 61. The pulley 63 slides on the upper support beam 61, and the upper support beam 61 gives a good guiding effect to the push-pull power connection mechanism, coordinating with the movement of the lower support body 2 and the support vehicle body 3.

[0038] As Figure 6 shown, cooling water tanks 46 are arranged on both the first power connection plate 41 and the second power connection plate 44.

[0039] The cooling water tank has a water inlet and a water outlet, and there are several partition plates 411 distributed in a staggered manner inside the cooling water tank 46. During the power conduction process, the push-pull power connection mechanism will generate heat, and the arranged cooling water tank 46 can effectively cool down the push-pull power connection mechanism.

[0040] As Figure 7As shown, the busbar connection a and the graphitization furnace connection b are positioned opposite each other, with the power transmission vehicle c positioned between them. The wheels of the vehicle body 1 drive the push-pull connection mechanism to align with the busbar connection a and the graphitization furnace connection b. The opposed dual-piston cylinders 45 operate, driving the first and second connection plates 41, 44 into close alignment with the busbar connection a and the graphitization furnace connection b. As the first and second connection plates 41, 44 engage, the support wheels 32 and lower support wheels 22 move, providing good guidance and smooth engagement. The connector 43 is made of flexible copper strip, which exhibits a certain degree of deformability. In this way, when the positions of the busbar power connection part a and the graphitization furnace power connection part b are not accurate, for example, they are not completely on the same plane, the connection part can provide a certain amount of deformation, so that the first power connection plate 41 can better fit the busbar power connection part a, and the second power connection plate 44 can better fit the graphitization furnace power connection part b.

[0041] The flexible connector 43 can compensate for displacement caused by mechanical vibration or movement by its own deformation, thereby maintaining the stability of the connection. When the connection surface is not completely flat, the connector 43 can adapt to the surface changes by its own deformation, ensuring good contact even on uneven surfaces.

[0042] The present invention is described above by way of examples, but the present invention is not limited to the above specific embodiments. Any changes or modifications based on the present invention fall within the scope of protection claimed by the present invention.
